Abstract

A self-luminescent display apparatus is provided. The self-luminescent display apparatus includes a self-luminescent panel, a display controller and an adaptive adjusting unit. The self-luminescent panel comprises self-luminescent elements and an allowed active region. When the allowed active region is configured to a first range, the display controller drives the self-luminescent elements in the first range to display an image frame. The adaptive adjusting unit configures the allowed active region to a second range according to a trigger condition, and scales the image frame to correspond to the second range. The adaptive adjusting unit controls the display controller to drive the self-luminescent elements in the second range to display an adjusted image frame, and controls the self-luminescent elements outside the second range to turn off.
